  • FastIngest is an open-source MIT-licensed bulk ingestion framework built for .NET.
  • Supports multiple databases including SQL Server, PostgreSQL, MongoDB, and Azure Cosmos DB.
  • Crossed over 1,600 downloads across 9 packages within its first 48 hours organically.
  • Optimized API designed for heavy write loads and high-throughput streaming data pipelines.

Developing data-intensive systems within the .NET ecosystem has traditionally involved dealing with fragmented approaches to bulk data ingestion. Different databases require entirely distinct boilerplate codes, performance tweaks, and custom error-handling strategies, forcing developers to write repetitive provider-specific implementations for every new project.

To solve this cleanly from first principles, a modular and high-throughput bulk ingestion framework for .NET has been introduced as an open-source project under the permissive MIT license, making it free for both commercial and non-commercial utilization without restrictive licensing hurdles.

Instead of relying on custom hacks for each new database provider, the framework delivers a unified, highly optimized API tailored for heavy write loads and streaming pipelines. The architecture provides broad native integration across various data storage models:

1,600+Downloads in first 48 hours
9Packages available on NuGet

Operating with a focus on efficiency, the suite organically surpassed 1,600 total downloads across 9 distinct packages during its first 48 hours of availability, all achieved without any formal public announcement or marketing push.

The emphasis on zero-allocation design in .NET bulk processing is crucial for modern high-performance architectures. By minimizing heap allocations, applications can drastically reduce Garbage Collector pressure, which is often the primary bottleneck during heavy database bulk insertions. Consolidating these optimized patterns into a unified abstraction layer allows engineering teams to maintain clean codebases while achieving native-level ingestion speeds across multiple database engines.

Developers building data migration tools, event stream processors, or high-throughput write services in .NET can find the packages on NuGet under aebibtech or inspect the source code via GitHub to integrate and evaluate the framework in their production environments.
